I would like to warn you to use extreme caution when ordering a replacement RV roof. There are products being sold in this market that would not be allowed on a commercial roof. Commercial roofing products are typically sold in .045 mil thickness and .060 mill thickness. They have a warranty of 10 to30 years and have over 40 years of performance testing on EPDM roofs. If this is the case for stationary commercial roofs, then why are replacement RV roofs being sold in .030 mil thickness? An RV is not stationary, and using thinner and improper material's will shorten the life of your RV roof.  

We need to remember that all RV rubber roofing technology originally came out of the commercial roofing market and their minimum standard for thickness for a commercial roof is .045 mil. So, now that you know more information, which would you choose: a thinner liner, or a thicker liner that is tested and proven with over forty years in the roofing industry?

We have been discussing different ways to save money when it comes to repairing or preventing leaks on your RV roof. If you have been trying to find something affordable to repair your roof with that you know will work, you're just in luck! Take a look at our Leak Prevention Kits, which comes in an Economy version and a Premium version. These kits come with just what you need to repair your leaky RV roof or to help prevent leaks from happening down the road. Take a look at the instructions below to see just how easy our kit is to use.

1. Thoroughly clean the detail of the roof that you are repairing with water and a mild detergent. Let the surface dry, then repeat the procedure with clean cloths until all the dirt and grime is removed. Allow the surface to dry completely.

2. Measure 4" from the center of the bar on each side and mark with a marker. These marks will show you where to apply your primer to ensure you have enough coverage for the tape.

3. Take your 2 ounce bottle of primer and shake thoroughly. While wearing gloves, apply primer to the marked area with the provided scrubber pad. Allow primer to dry. For best results, repeat primer application after the first layer of primer is dry. Be sure you apply primer on both sides of the bar, and anywhere you are going to be placing tape.

4. Position tape over the center of the bar and remove the backing paper. Apply the tape over the marked areas, trying to keep over the center of the bar. When you get to the end of the roof, cut off the excess tape and save it for future repairs you may have.

5. Once you have the tape applied, take your seam roller and roll over the tape to help ensure adhesion. Be sure to roll over the edges to make sure they are down.

6. After you have rolled over the tape, you can take the caulk and run a bead down the end of the tape. This is not necessary, but it does give you added protection. You can use the leftover caulk to go down the sides of the tape, too, but you may not have enough to cover the entire piece. You can always order an extra tube of caulk to give you some extra leak protection. 


The cured roofing tape in our Leak Prevention Kits is the same roofing tape that has been used in the roofing industry for the past 40 years. It is tried and true, so wouldn't you want to use something that you know has the reputation of being reliable?

A popular repair on RV EPDM roofs is using coatings, which are supplied by many different manufactures. People think that using coatings to repair your roof is the easiest of all the repairs available. The instructions will start by telling you to thoroughly clean the membrane before you apply the product. Then you will need to measure out the area on the roof to be repaired; for example, you would measure out ten square feet, forty square feet, or one hundred square feet, depending on what you were repairing. They will tell you that one gallon of their product should cover a certain amount of square foot. Lets say, as an example, one gallon covers 100 square feet, .020 mil thick; when you finish applying one gallon, you should be around 100 square feet in coverage. You will use a squeegee or a paint roller to apply their product. So you have applied the product over the area you measured, and your bucket is empty; this means everything worked out as planned, right? Unfortunately, you do not know that for certain. How do you know if you have an equal coating over the entire roof? You could very easily have it thicker in some places than others; some places may have it .040 mil thick while others have only .010 mil thick. Even professionals have trouble being sure the coating is even over the entire roof. This is a major weakness when it comes to installing coatings over an existing roof. Fast forward to five years down the road, when you realize your roof is failing in certain areas. Say you have a warranty and the company asks for a sample; if the sample you send them is only .010 mil thick instead of the specified .020 mil thick, they will tell you that you have applied the coating wrong.

It would seem you are successful because you applied just the right amount of coating for the amount of square feet the instructions told you. But this would not be a true statement, because how would know that you had an equal amount of coating over all of this area? You could very easily have it .040 thick in places and as thin as .010 mill in others. There is no true way to gauge and install the same thickness all over the roof. Even professionals have trouble in making sure that you have met the minimum thickness requirements for the coating products. This is a major weak spot in installing coatings over any existing roof. If you have a warranty problem and they ask for a sample of the failed area and it is only .018 mil thick instead of the specified .020 mil thick they could deny your warranty claim.

This just goes to show you that the "easiest" solution is not always the best solution..

Never! Never! Never! use a tape product that is not designed specifically for your EPDM rubber roof on your RV. There are many different products that are sold to repair your RV roof but you should use only those that are made out of the same EPDM material. Remember that all EPDM roofing  technology and repair procedures were developed by the commercial roofing manufactures. As we have stated previously, they are only two manufactures of this product in the U.S.: Carlisle Syntec Systems and Firestone Building Products. Their roofing systems have warranties up to thirty years on a roof. This is an extreme amount of time to be exposed to possible failures, so they do years of research and testing to make sure their products will perform. Never use any caulking that is not EPDM or butyl based.
